4 Claims. (Cl. 242-72 Our invention relates to structuresdesigned toreceive strip and wire material, such as steel, and to rotate with theetfect of winding the material into'a roll. Various machines have beendevised for this purpose and designed to be adjustable in respect to theoriginal diameter or inner size of the roll to be formed. However, suchmachines as have come to our attention do not carry a drum which issuitable for the winding of strips 'of different widths, and one objectof the present invention therefore is to provide a winding drum whichhas this advantage.

A further object is to provide a winding drum which is easily mountableon the conventional winding machine and made fast to the machine by theadjustment of the same.

Another object is to design the novel winding drum as a flexible unitwhich is expansible to render the drum rigid for the support of thework.

An additional object is to construct the novel winding drum along linesof simplicity and easy application to the conventional winding machine.

With the above objects in view, a better understanding of the inventionmay be had by reference to the accompanying drawing, in which- Fig. 1 isa front elevation of the winding drum as mounted on the winding machine;

Fig. 2 is a view from the right-hand side of Fig. 1; and

Fig. 3 is an enlarged section on the line 33 of Fig. 1.

In accordance with the foregoing, specific reference to the drawingindicates the standard of a conventional winding machine at 10, and thebase thereof at 11. The machine has a headpiece 12 which journals ashaft 13; and a gear 14 is mounted on the frontal portion of this shaft.The shaft also carries a suitable bearing 15 for a set of radial screws16 whose inner ends carry pinions 17 which are in mesh with the frontalside of the gear 14; and the screws carry a set of traveling nuts 18which are extended forwardly with arms 19. The gear 14 may be madestationary by means of a key or pin 20 passing through the gear hub andinto the headpiece 12, or by some other suitable mechanism. In thisevent, rotating the bearing 15 in order to revolve the screws 16 willcause the pinions 17 thereof to roll around the gear 14 and rotate thescrews at the same time. The effect will be the gathering or separationof the arms 19.

Usually, when work is to be wound on the machine, the arms 19 aresituated at the proposed internal diameter of the work; and they areseparated as just described in order to make the work fast to the set ofscrews. Then, when the winding is to begin, the pin 20 or othermechanism is withdrawn to release the gear from the headpiece, and thelatter made tight to the shaft 13, so that the rotation of the latterwill operate the winding assembly as a whole.

The present invention has no operative connection with the mechanism ofthe winding machine, applying only to the arms 19 thereof. In otherwords, the invention is intended to be mounted on the said arms and tobe made 2,729,403 Patented Jan. 3, 1956 fast on the same when they areexpansively adjusted. Specifically, the novel winding drum consists ofthree basic parts, namely, a frontal plate 25, a back plate 26, and afrontal band 27. The plates 25 and 26 are of sufficient thickness'to berigid, yet light enough to enable the winding drum to be carried aboutreadily; and the plates are both of circular form and concentricallyarranged.

The plates 25 and 26 are attached to each other in spaced relation.Thus, Fig. 3 shows a spacing unit employed, the same consisting of adisc 30 which is extended from one face with a shank 31 which isriveted, as indicated at 32, to the plate 26. The thickness of the disc30 represents the spacing distance for the plates; and the plate 25 isattached to the disc by means of a screw 33 threaded into the disc asshown. Fig. 1 shows that this spacing expedient is employed at sixcircularly spaced points to hold the plates together evenly.

The plates 25 and 26 are made with central openings 35 of the samediameter; and the band 27 is positioned in front of the plate 25, andwith the rear edge of the hand even with the rear face of the plate. Theband is of spring steel and normally contracted to a size materiallyless than the diameter of the openings 35, so that the ends of the bandare closely spaced, as indicated at 36. However, it is possible toexpand the band until it fills the opening 35 in the plate 25, so thatthe wall of the band will lit the plate, as clearly shown in theright-hand central portion of Fig. 3.

The band 27 is fioatingly supported in relation to the plates 25 and 26when the band is in the contracted position shown. This support isgained by welding 2. lug 37 to the rear of the drum wall, as shown at 38in Fig. 3, to dispose the lug 37 in a plane crosswise of the band axis.The ing 37 is made with an opening 39 to receive one of the spacer discs30, as shown in the figure just referred to, so that the band becomespivotally supported between the plates in this manner. In order that thedrum may not swerve laterally, it is extended with lugs 40 and 41 atpoints distant or across from the lug 37, such lugs extending from theband into the space between the plates 25 and 26.

It is apparent that the band 27 is of considerable width, so that it mayserve as a winding spool for material which is either narrow or wide.When such service is required, it is only necessary to gather the arms19 of the winding machine to an extent to be received inside the band 27as the novel winding drum is backed toward the winding machine 10. Thelatter then is operated to separate the arms 19, this action expandingthe band until it fits tightly in the opening of the plate 25. Thewinding drum now is rigidly attached to the rotary assembly of thewinding machine and may receive the work 50 by having the foremost endof the same hooked over the leading end of the band.

It will now be apparent that the novel winding drum is a highlyefiicient mounting for the winding machine. While it requires nooperative connection with the mechanism of the same, it becomes a partof the winding machine by simple application to the projecting arms 19thereof and the expanding of the same to make the winding drum fast.Now, the arms 19 alone are not depended upon to receive the work, butthe wide and circular unit 27 is present to receive material of anysuitable width, and to form the same into a roll without the need ofaccurate alinement between the supply zones and the winding drum.Further, the plate 25 is large, offering a corresponding capacity forthe work. Further, the large size of the plate 25 also gives it thefunction of a guard to prevent the material wound from getting in theway of the mechanism of the winding machine. Further, the

provision of the two plates 25 and 26 not only makes for the rigidity ofthe winding drum, but also provides a uniform bearing for the band lugs37, 40 and 41. Finally, the novel winding drum is made up of parts whichare few and simple, so that it may be produced economically and easilyhandled for application to or removal from any winding machine availablefor a given job.

While We have described the invention along specific lines, variousminor changes or refinements may be made therein without departing fromits principle, and we reserve the right to employ all such changes andrefinements as may come within the scope and spirit of the appendedclaims.

We claim:

1. A winding drum adapted for mounting on the expansible arms of a stripor wire windingmachinc comprising a frontal plate, a rear platespacecily attached to the frontal one, both plates having openings insubstantial registration, a band situated forwardly of the frontal plateand being expansible to engage its rear portion with the rim of theopening in the frontal plate, an element attaching the band for freemotion at a point between the plates, and other elements extendedbetween the plates distantly from said point for maintaining thealinement of the band with the plates.

2. The structure of claim 1, one spacing means for the plates being acircular disc, and the first element being a lug extended from the bandto pivot about said disc.

3. The structure of claim 1, said other elements being lugs extended atpoints opposite the first element to project into the space between thediscs.

4. The structure of claim 1, said elements comprising lugs attached toone end of the band in a plane transverse of its axis.
